Given numbers are 438,516,127,122

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 438,516,127,122 is 291813996.

Find LCM of 438,516,127,122 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 73 x 86 x 127 x 61 = 291813996

Therefore, the lowest common multiple of 438,516,127,122 is 291813996.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

438 x 516 x 127 x 122 = 3501767952

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

438 : 1, 2, 3, 6, 73, 146, 219, 438

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

127 : 1, 127

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,516,127,122, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

516:2x 2x 3x 43

127:127

122:2x 61

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 3501767952/(1x12)

LCM = 3501767952/12

LCM = 291813996

Thus, we can understand that the LCM of 438,516,127,122 is 291813996.
